In RawMesh.cpp, there are two functions called IsValid and IsValidOrFixable. A user has reported that there may be an issue here where IsValid can be true while IsValidOrFixable is false.

From looking at the code, IsValid can accept either an empty array for FaceSmoothingMasks or the correct amount, which is equal to NumFaces. IsValidOrFixable on the other hand will not accept an empty array and will only accept an array of a size equal to NumFaces.

The relevant lines of code can be found from lines #27-98 in RawMesh.cpp
